Gas concentration detector is a gas leak detection instrumentation tools, including: portable Gas Detector
, portable gas detector, Fixed Gas Detector
, on-line gas detector, etc.Gas sensors are used to detect the types of gases in the environment. Gas sensors are used to detect the composition and content of gases.
It is generally believed that the definition of a gas sensor is based on detection of target classification, that is, those who used to detect gas composition and concentration of sensor is called gas sensor, whether it is to use physical methods, or with chemical methods.For example, detection of gas flow sensor is seen as a gas sensor, but it belong to important thermal conductivity type gas analyzer gas sensors, although they sometimes use broadly consistent detection principle.
